CVE-2026-72698

Grav CMS before 2.0.16 fails to filter system, site, and theme configuration arrays in sandboxed Twig renders, allowing content editors to read sensitive configuration values. Attackers with page-content edit access can access raw configuration arrays including secrets like cache credentials by using dot notation in Twig templates, bypassing the config_denied_paths restrictions.

Summary		(es) Grav CMS anterior a la versión 2.0.16 no filtra los arrays de configuración del sistema, del sitio y del tema en las renderizaciones Twig en entorno aislado, lo que permite a los editores de contenido leer valores de configuración sensibles. Atacantes con acceso de edición de contenido de página pueden acceder a arrays de configuración sin procesar, incluyendo secretos como credenciales de caché, usando la notación de puntos en plantillas Twig, eludiendo las restricciones de config_denied_paths.
